taken in his original sense, where it is not the most representative member of Naucoria but the first cited. Nevertheless its designation as lectotype cannot be considered as an automatic choice and cannot be rejected for this only reason. If considered an Alnicola, Ag. escharoides would be the only Alnicola species included in Naucoria Genuini by Fries all over his opera, all the others belonging to other "tribes". The choice of this lectotype for Naucoria would drive to a complete amending of Naucoria according to Fries’ (1821) concept, which excludes all initial taxa but one, and moreover not the most representative one. Finally, Ag. escharoides has already been proposed as a neotype of Alnicola (Konrad, 1934). For all these reasons the author proposes to reject Ag. escharoides as a lectotype for Naucoria. It should be mentioned that 3 other collections from Femsjö were collected by M. Moser, labelled as "Naucoria sp.", and another identified "Naucoria sphagneti P.D. Orton" (herb. Moser, IB). This illustrates the diversity of Swedish Alnicola, not perceptible in Fries’ opera who probably could not separate them reliably on macroscopical characters only. This is also illustrated by a plate of Ag. escharoides directed by Fries (S) in 1854, which might represent Inocybe calospora Quél. Agaricus conspersus Fr.: Fr. is eligible as lectotype of Naucoria, but has never been proposed. Unless Fries has modified his acceptance of this taxon after 1821 (Fries, 1836-1838: 210; see above, Ag. escharoides), it is now considered by all authors as a member of the genus Tubaria (W.G. Sm.) Gillet. As Tubaria has been the first genus separated from Naucoria (Gillet, 1876: 540) and contains presently more than 60 taxa worldwide, a lectotypification of Naucoria by Ag. conspersus would uselessly force to introduce a considerable number of new combinations, against the recommendations of the Code of Nomenclature regarding nomenclatural stability. This possibility is rejected here. Agaricus siparius Fr.: Fr. has been proposed by Romagnesi (1950), on the basis of his own interpretation of this taxon (Romagnesi, 1942; in Kühner and Romagnesi, 1957). According to Romagnesi (loc. cit.), N. siparia ss. Romagn. might be a synonym of N. ferruginea R. Maire (now Tubaria, Phaeomarasmius or Flammulaster: Watling, 1967; Horak and Moreau, 2005). According to Orton (1960) and Vellinga (1994), it is an autonomous species of Flammulaster. Agaricus siparius is the closest species matching Fries’ diagnosis of Naucoria (1821: 261) and would certainly be the best candidate for an orthodox lectotypification of Naucoria. But considering the still uncertain interpretation and systematic position of Ag. siparius, and the nomenclatural consequences of such an uncertain choice, it is proposed not to adopt it. 128
Fungal Diversity Ag. pannosus Fr. : Fr. has not been interpreted in the recent literature, but fits in well with the original diagnosis of Naucoria; the only restriction is that the cap is described “squamis destituto” and therefore classified in the 4 th group of Naucoria sect. Lepidoti, when Ag. escharoides, Ag. siparia and Ag. conspersus are classified in the 3 rd section (Fries, 1836-1838, 1874). However, this is not contradictory with the protolog and it has always been considered by Fries, from 1821 to 1874, as a typical member of Naucoria (sect. Lepidoti). Therefore it figures as a perfect residue according to the recomm. 9A5. It is not risky to propose Ag. pannosus as a lectotype of Naucoria, since it should not destabilize any of the well-defined and currently accepted genera Alnicola, Flammulaster or Tubaria.
